New Features

Support for SASL Authentication

Some installations of memcached are not in controlled environments where simple network filtering keeps bad guys out of your stuff. To help with those other environments, we've introduced SASL support. You can read more about it here:

http://code.google.com/p/memcached/wiki/SASLHowto

New perl tool `damemtop` in scripts/

dormando's awesome memcached top - a new commandline perl tool for monitoring small to large memcached clusters. Supports monitoring arbitrary statistics. See scripts/README.damemtop for more information.

This tool is intended to replace memcached-tool, but not yet.

Also Noteworthy, Slab Optimizations

Objects on the larger end of the limit should be generally more memory efficient now as more slabs are created (thus are more granular).
